1. Get it down to 30s. There is a lot of fluff that could be tightened up. 25s too long as is, cut the length of the confetti explosion, the long shot on the cat, etc..
2. Show off more of the interactivity. If I'm going to pay $2 for a virtual good outside of a game it needs to have some staying power. Show it off.
3. I'd add faces or something to show that the iPods are owned by 2 different people. It is pretty clear, but I was just watching in a small window with partial attention and I could see someone being confused.
